Ah, love it when the sleep gets messed up! I hope you went to bed earlier or at least got better quality sleep (not having to worry about getting up in the morning or what you had to do). I'm retired so don't mind the 3 or 4 am wakings, I can go back to sleep or take a nap later or go to bed earlier, etc. without worrying I will mess up a schedule. I was up a little earlier today because I'm expecting a delivery between 9 and 11 (obviously not 9 or 9:30 :-) but I feel like I got enough sleep.
